Brief Summary

This is an open-labeled, single-arm, multiple-dose escalation and single-dose expansion clinical study of cell therapy to observe and evaluate the safety and efficacy of c610 injection in the treatment of patients with advanced solid tumors.

Detailed Description

Primary Objection:

1. The mainly purpose of dose-escalation stage is to observe and evaluate the safety and tolerability of c610 injection in patients with advanced solid tumor, including the dose-limited toxicity(DLT) and the maximum tolerated dose (MTD).

2. The mainly purpose of dose-expansion stage is to evaluate the safety and efficacy of c610 injection in the treatment of patients with advanced solid tumors.

3. To evaluate the objective remission rate (ORR) and disease control rate (DCR) of 3 months according by the Response Evaluation Criteria in Solid Tumors (RECIST version 1.1)

Secondary Objection:

1. To observe the pharmacokinetic (PK) characteristics of c610 injection in patients with advanced solid tumors and its retention in peripheral blood;

2. To evaluate the progression free survival (PFS), overall objective response rate (ORR), duration of response (DOR), and overall survival (OS) according by the Response Evaluation Criteria In Solid Tumors (RECIST 1.1);

3. To observe the change in cytokines release before and after c610 injection treatment;

4. To observe the variation of tumor biomarker before and after c610 injection treatment (e.g. prostate cancer serum PSA).

Exploratory objection:

To investigate the potential biological indicators of blood and tumor specimen, including ctDNA (circulating tumor DNA) sequencing, immune repertoire sequencing (tumor tissue is prior for single-cell sequencing), ADA and RCL detection.

Conditions

Advanced Solid Tumors

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

All the subjects enrolled will receive the experimental intervention, c610 injection

Group Type: EXPERIMENTAL

c610 injection

Intervention Type: DRUG

Peripheral blood mononuclear cells (PBMCs) are used for cell preparation. PD-1 positive T cells are isolated from peripheral blood by blood cell apheresis method and transduced with lentivirus loaded with enhanced receptors. The obtained c610 is used for one-time intravenous infusion.
